I have seen some drives that R_ERR in the middle of a DMA transaction and then don't send the FIS to update the shadow registers in the controller. You could be seeing this problem, but you'd need to look a SATA bus trace to be sure. -----Original Message----- From: Hale Landis [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 09, 2003 9:32 PM To: T13 List Server Subject: [t13] SATA question This message is from the T13 list server. What causes a PCI bus SATA controller to stop responding in the middle of a command? Specifically, in the middle of a READ DMA command, what would cause the drive status to change to FDH or FFH and then cause the controller and drive(s) to ignore a Soft Reset and continue to return status of FFH for all reads of any ATA register?
